Metabolomics analyses of two GMO maize events

Researchers from the French GMO90+ project published results of metabolomics analyses of field-grown harvested grains of two GMO maize events -MON810 and NK603- and feeds derived from them and compared them with non-GMO samples. The majority of statistically significant differences in grain composition could be attributed to the combined effect of genotype and environment. In comparison, transgene and glyphosate effects remained limited in grain for the compound families studied. Some but not all compositional changes observed in grain were also detected in grain-based diets formulated for rats.
